AGG is updated. The major news is there the
Scanline based Polygon Boolean Algebra is added,
that is, calculating of Union, Intersection, XOR, and
Difference of arbitrary polygons. It uses the
Scanline approach and in typical screen resolutions
works much faster (about 10 times) than vectorial
algorithms like GPC by Alan Murta. It preserves
perfect Anti-Aliasing and besides, can operate with
semi-transparent polygons.
